Embodiment 1
[0021] like figure 1 As shown, an unpowered aircraft includes a body 1 made of soft elastic material. The body 1 includes an inner layer 10 and an outer layer 11 arranged inside and outside, a gap 13 is provided between the inner layer 10 and the outer layer 11, and a connecting portion 12 connecting the inner layer 10 and the outer layer 11 is provided in the gap 13, and the inner layer 10 It is a hollow structure. The main body 1 is provided with an inflation hole 110 , the inflation hole 110 communicates with the gap 13 between the inner layer 10 and the outer layer 11 , and the inflation hole 110 is provided with an inflation two-way valve 2 . After the inflatable two-way valve 2 is opened, air is inflated into the gap 13 through the inflation hole 110, and the air in the gap makes the outer layer expand outwards. When it expands, the connecting part pulls the inner layer to expand together, changing the relative volume of the inner layer 10. The air is expelled, and the...
Embodiment 2
[0031] like figure 2 As shown, this embodiment is basically the same as Embodiment 1, the difference is:
[0032] The main body 1 may also be provided with an air extraction hole 100 , the air extraction hole 100 communicates with the inner layer 10 , and an air extraction two-way valve 3 is provided on the air extraction hole 100 .
[0033] When the unpowered aircraft of this embodiment is put into use, the inner layer 10 can be in an inflated state, and the inside can be filled with air. When adjusting the operation of the suction two-way valve 3, the air in the inner layer 10 is discharged out of the body 1 through the air suction hole 100, and the volume of the inner layer 10 is reduced; at the same time, the inflation two-way valve 2 is adjusted so that the air enters the gap 13 through the inflation hole 110, When inflation is realized, the gas filled in the gap 13 generates pressure, which makes the body 1 expand as a whole, and the expansion process makes the outer l...
